When girls reach a certain age, they experience uterine bleeding once every month, which is called menstruation, and the first menstruation is called menarche. Menstruation is a sign of female maturity and a sign of fertility. There are some women who do not know how to take care of menstruation, and they always find it more unlucky and troublesome. In fact, this is also something that women must go through when they grow up. So, is it normal for a twelve-year-old child to come to menstruation?
It is normal for a twelve-year-old child to have menstruation. Most girls have menstrual periods between 11 and 14 years old. In recent years, the age of menarche has tended to advance. Because everyone has different physiques and different nutrients they usually take in, the earliest age of tide will be 11 years old, and the late tide will be around 16 years old.
If a girl has menstruation before the age of 10, most of it is caused by precocious puberty. If a girl is over 16 years old and has not had menstruation, it is usually caused by developmental delay. It is best to go to the hospital to confirm the diagnosis through a systematic examination.
Menstruation is affected by many factors, and the specific conditions vary from person to person. Due to the high standard of living and good nutrition, they are generally younger at menarche. Menstruation is also related to climate. Generally speaking, girls in cold regions have a late menarche age. If girls often like to eat junk food, especially fried chicken legs, hamburgers, etc., usually the estrogen level in the body is relatively high, then menstruation will come earlier.
